Contra Costa County Inmate Search

In Contra Costa County, California, breaking a law or ordinance can result in detention, arrest, or incarceration after prosecution. Incarcerated persons will serve time in the county jail or state prison, depending on the severity of their offense. Interested persons may look up information on Contra Costa County inmates pursuant to the provisions of California law on the dissemination of Contra Costa County Public Records.

According to Cal. Pen. Code § 834, an arrest is defined as the lawful detention of a person. This occurs when a private person or peace officer witnesses or hears a crime or public offense. Additionally, arrests occur when a warrant is issued and when an officer has probable cause to believe a person has committed an offense. After an individual is arrested in Contra Costa, the individual (the defendant) may undergo a booking procedure during which an official arrest report will be generated.

Consequently, one of these situations may occur:

  • The individual will be released if no charges are filed by the prosecutor.
  • The individual will be required to post bail/bond or will be released with the promise to appear for arraignment at a later date.
  • The individual will remain in custody and be transferred to the trial court for arraignment by the police.

Depending on the charge and case details, a trial court may impose incarceration on a defendant, sending them to a local jail or state prison for a brief or lengthy period. Depending on the severity of crimes and court sentences, arrested fellows or offenders may be housed in one of the three primary Contra Costa County jails operated by the Contra Costa County Sheriff's Department:

  • The Martinez Detention Facility (MDF)
  • West County Detention facility (WCDF)
  • Marsh Creek Correctional Facility (MCDF)

In some cases, arrested fellows may end up on the Custody Alternative Facility programs, supervised by the Contra Costa County Office of the Sheriff. Inmates serving sentences over one year or convicted of felony offenses may be sent to a state prison under the purview of the California Department of Corrections and Rehabilitation (CDCR).

Inmate records are considered public in the United States and therefore are made available by both traditional governmental agencies as well as third-party websites and organizations. Third-party websites may offer an easier means to search, as these services do not face geographical limitations. However, because third-party sites are not government-sponsored, the information obtained through them may vary from official channels. To find inmate records using third-party aggregate sites, requesting parties must provide:

  • The location of the sought-after record, including state, county, and city where the inmate resides.
  • The name of the person listed in the record, unless it is a juvenile.

Where to Find a Contra Costa County Inmate Locator

An inmate locator is a search engine that provides information on inmates housed in a particular region or jail/prison facility. As a public service to promote community safety, local, state, and federal correctional agencies often provide inmate locators services.

The Contra Costa County Inmate Locator is accessible through the county sheriff’s website. However, to use the locator, the user must be searching for a contra costa county jail inmate, and also possess the inmate's last and first names. In addition, other search parameters such as the inmate's date of birth and middle name might be required.

Additionally, a person can access the Public Inmate Locator maintained by the California Department of Corrections and Rehabilitation, if an inmate is booked into the state prison system despite being located in Contra Costa County. When necessary, The Custody Services' Transportation Unit transports these inmates to and from the state prisons and mental health facilities in California.

In addition to inmate locators provided by correctional agencies, third-party public records websites may provide search tools to assist the public in retrieving inmate records. Typically, the search criteria for these websites are an inmate's first or last name and the name of a U.S. state. However, it should be noted that a fee may be required to view a record (this fee varies by site).

How to Visit a Contra Costa County Inmate

Inmates serving sentences in the majority of Contra Costa County Jails are permitted one or two visits per week, with each visit lasting between 15 and 30 minutes. Up to three or four visitors may visit an inmate at the same time, and all visitors must be scheduled and enter the facility at least 30 minutes prior to the end of any visiting block. This is due to the fact that scheduled visitor registration will begin 30 minutes prior to the posted visiting time. Visitors must have their visit slip time-stamped and in the tray 30 minutes before their scheduled appointment.

The visiting inmate is responsible for notifying the supervising Deputy Sheriff and is required to report to the visiting area 15 minutes prior to the scheduled visit. Failure to comply with these rules will result in the visit being canceled. In some instances, the Facility Commander may exclude Visitors from visiting activities due to previous misconduct.

Visits may be conducted in person or via video, and visitors must follow the visitation rules regarding registration, clearance, entrance, screening, and departure. Generally, all visitors must arrive 30 minutes ahead of their scheduled visit time, and complete a visitor’s form before approaching the Visitor Registration Desk. The registration form must be complete, legible, and contain basic information on identity, the inmate's relationship to the registrant, and the inmate's name and booking number.

Visitors are to present their completed visitor form with an acceptable photo identification at the Visitor Registration Desk.

Acceptable forms of identification include:

  • A photo driver's license
  • Department of Motor Vehicles photo identification card
  • Passport with photograph
  • Military identification card with photograph
  • Picture identification cards issued by the U.S. Department of Justice
  • Picture identification cards issued by any foreign government agency that also contain physical descriptors and birth date.
  • Parents and/or guardians of minor children are required to present a birth certificate or proof of guardianship during the initial visit processing.

The Visiting Aide will document the documentation of the birth certificate in the inmate's visiting file and return the original documents to the visitor upon receipt of the completed visitor form and acceptable photo identification. The inmate should inform the visitor beforehand of any required documents to bring with them.

Contra Costa County Probation and Parole

The courts in Contra Costa County offer probation as an alternative to incarceration for convicted offenders. Rules 4.413 and 4.414 of the California Rules of Court, outline the criteria by which local and state courts determine whether or not to grant probation. According to these regulations, a large number of defendants are presumed to be eligible for probation, unless probation is prohibited for their offense.

Formal and informal types of probation exist in California. The Penal Code refers to informal probation as a "conditional sentence," but lawyers and judges typically refer to it as court probation or summary probation. The primary distinction between informal and formal probation is the method of supervision.

In Contra Costa, the Contra Costa County Probation Department is the local agency that supervises court-ordered probation in Contra Costa. The Probation Department monitors probationers to ensure they comply with court-ordered conditions in order to avoid jail time and other punishments. The Probation Office carries out probation orders, engages in community-based supervision, and strives to reduce the likelihood of recidivism. In addition, they assist in the rehabilitation of both adult and juvenile offenders through any of the programs at John A. Davis Juvenile Hall and the Orin Allen Youth Rehabilitation Center.

On their website, the Contra Costa County Probation Administration provides additional details about their adult and juvenile probation services. Additionally, individuals can contact the Probation Information Center via one of the following channels:

  • Fax: (925) 313-4191
  • Phone: (925) 313-4000

Parole, on the other hand, is a correctional program that permits a felony inmate in a California state prison to be temporarily or permanently released prior to the completion of their sentence, on the condition that they maintain good conduct in the community (Contra Costa County) and fulfill specific responsibilities. The parole process in California is outlined in Sections 3040 to 3073.1 of the California Penal Code.

Inmates must meet the eligibility requirements for parole, after which the California Board of Parole Hearings grants or denies the petition. An offender granted parole will be expected to live in the county where they last legally resided before their incarceration. They must also report to their parole officer in person at scheduled times.
